The rCUDA Team will release rCUDA v15.07 during the ISC'15 exhibition at Frankfurt. The new rCUDA version provides support for CUDA 7.0 along with support for dual-port InfiniBand cards. The cuDNN CUDA library is also partially supported. Notice the change in the version number policy, which is now based on the year and month of the release.
